ROLLING-MACHINE.-

SPECIFICATION forming part of Letters Patent No. 727,2?7, dated May 5, 1903.

Application filed August 18, 19021 Serial No. 120,152. (No model.)

To all whom, it may concern: M

Be it known that I, O'rro WINDECKER, a subject of the German Emperor, residing at Kaiserslautern, Rheinpfalz, Germany, have invented certain new and useful Improvements in Rolling-Machines, of which the following is a specification.

This invention relates to rolling-machines- Figure l is a front elevation, while Fig. 2

is a side elevation corresponding thereto.

Fig. 3 is a detailed sectional elevation of one of the rollers and the shaft upon which it is mounted.

In carrying the invention into effect I mount" rollers, such as Cb b, so that they may have any axial movement imparted to them in addition to the movement of rotation. The metal block, blank, or billet g, previouslyheated, is placed between the rollers a b and passes forward on the rotation of ,the rollers'in'anaxial direction. Simultaneously with this movement the block, blank, or billet g is by the axial movement in opposite directions of the rollers a b rotated and caused to move' from left to right, so that the block, blank, or billet is rolled circumferentially and re dnced.

The rollers a b are mounted'upon shafts 0 and 1;, respectively, being connected thereto by means of keys 0. Keyways are provided in the rollers, by means of whichthe rollers may slide upon the shafts and upon the'keys, so as to be compelled by the keys to rotate with the shafts.

The displacement of the rollers during.

their rotation is efiected by means of levers h, arranged on each side of the machine, through rods 8, deriving reciprocating motion from respective toothed wheels m m, which gear with pinions n n, mounted upon the counter-shaft w. The counter-shaft w is continuously rotated by means of belting or by gear.

The links 1' v, are pivotally connected to the lever h, and their opposite extremities are pivotally connected to a bar 1), which serves to connect together the two rings 4' and 25, respectively provided on each side of the rollers. The rollers a and b are cut down at each side for the reception of the rings 1" and t aforesaid, and these rings are provided at diametrically opposite points with pins or projections en= gaging within holes provided in the respective extremities of the bars 19. The rings r and f are thus held against rotation with the rollers a and 1),- upon which they are mounted, and serve to effect the axial movement of said links, this movement being communicated to them by the links t, which are connected to the bars 19, as illustrated.

It will be understood that the arrangement is such that on the movement of the lever h -by means of the connecting-rods s the respective links 1' causethe rollersto move axially in opposite directions. I

The rotation of the rollers is effected by ordinary gear, as illustrated in the drawings, in which a worm 7.: on the counter-shaft "to causes the rotation of the worm-wheel d,which is keyed upon the same shaftas the pinion e. The pinion 6 gears with the pinion y, arran ged on the lower shaft 1;, and also with theintermediate pinion e, which gears with the pinion w, arrangedon theupper shaftfo. It will thus be understood that while a slow rotation is given to the respective rollers it-b, by means of which the block, blank, or billet g is slowly fed forward, a relatively quick lateral movement in opposite directions is given to the rollers, by means of which the block, blank, or billet is rolled cylindricallyand the formation of flat faces upon the block, blank, or

billet is avoided. 4

Means may be provided for the adjustment of the lateral movement of the respective rollers as required according to the size of the cylindrical body to be formed or according to the dimensions of the blanks, rods, or tubes to be rolled.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. Apparatus for rolling cylindrical bodies in combination, rollers between which the cylindrical body is longitudinally fed, rings at the respective ends of said rollers, bars conon each side of the pivotal center thereof, and means-for reciprocating said levers.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

OTTO WINDEOKER.
